Animal Dreams by Barbara Kingsolver Codi Noline, her self-confidence flagging after failures in med school and in a relationship, returns home to Grace, Ariz., where she renews a romance, comes to understand her father and worries about her sister, Hallie, who is helping farmers in Nicaragua. This is portrayed in a series of flashbacks for both Codi & her father who is declining from Alzheimers. It is so well written. I read it so long ago when I lived in Tucson so it was fun to read it again.
